Re: rand() function performs poorly

:When you run that code, it will print "OoOoOoOo..." without any change;

    I think you are talking about /usr/src/lib/libc/stdlib/rand.c, but
    I don't think FreeBSD-4 or FreeBSD-5 has fixed that.  They committed
    something but it looks like they backed it out.

    Most people use the random()/srandom() facility rather then the old
    rand() facility, or use /dev/urandom.  The old rand() facility 
    is severely limited due to API requirements and constraints.
